Measuring the success of global oil and gas corporate mergers and acquisitions from a financial perspective

ENGLISH ABSTRACT: Successful merger and acquisitions (M & A) from a financial perspective increases shareholder value. This paper examines the effect of corporate mergers and acquisitions (M & A) on shareholder value. A discussion on shareholder value follows with reasons why companies choose M & A as a growth strategy. The type of M & A strategy affects the value it creates. A literature review of M & A activity during the five periods in the twentieth century, referred to as merger waves, provides an understanding of the conditions which precipitate M & A activity. However, failure of companies that engage in M & A activity has not resulted in a decline in the popularity of M & A. This study identifies and subsequently analyses data (profitability ratios) on 34 upstream oil and gas companies that have engaged in M & A activity. Profitability ratios indicate the financial performance of a company and ultimately shareholder value. In order to obtain the best possible insights into the behaviour of the identified variables and their impact on shareholder value, the specific variables are empirically tested over different time periods through the application of two statistical tests performed on the data. The empirical analysis is based on a total of 324 observations gathered by Evaluate Energy for global oil and gas companies and covers the period 1995 to 2005.The results of the different testing methods, although subject to certain limitations, give reason to believe that the M & A leads to an erosion of shareholder value. Hence the appropriate reasons for embarking on an M & A strategy and the comprehensive pre-acquisition evaluation thereof, is tantamount to M & A success.
